    Within a few years,he had dne just that.He’d develped a disease-resistant strain f wheat that culd yield high numbers f plants and was a fast grwer.He then realised that by cmbining mdern agricultural prductin techniques,the strain f wheat culd be intrduced t develping natins such as Mexic,India,and Pakistan.Befre lng,Mexic became an exprter f wheat.A few years later,wheat prductin had dubled in Pakistan and India;as a result,fd prductin had greatly imprved.
    The intrductin f these disease-resistant wheat strains led t what is nw knwn as the Green Revlutin,a perid when the prductivity f glbal agriculture increased as a result f new advances.Befre Nrman Brlaug’s innvatin,it had been predicted that mst f the ppulatin f India wuld be dead befre 1980.The ppulatin was grwing at a faster rate than their resurces culd keep up with.It was nly thanks t the Green Revlutin that the peple managed t survive.It is estimated that withut Nrman Brlaug’s wrk,ver a billin peple wuld have died. 
    In 1964,Brlaug was named the directr f the Internatinal Winter Wheat Imprvement Prgram,as well as the Cnsultative Grup n Internatinal Agricultural Research’s Internatinal Maize and Wheat Imprvement Centre (CIMMYT).He served fr 13 years as president,befre stepping dwn t senir cnsultant③.During his 13 years at CIMMYT,the cmpany expanded their research t include ther types f crps.After stepping dwn frm CIMMYT,Brlaug c-funded the Wrld Cultural Cuncil,which aims t prmte culture,values and gdwill.Fr his cntributin t humanitarian④effrts and increased wrld fd supply,Brlaug was awarded the Nbel Peace Prize in 1970.
    词海拾贝①genetics n.遗传学②sustainable adj.可持续的③cnsultant n.顾问④humanitarian adj.人道主义的典句欣赏1.His hpe was that he culd create sme srt f sustainable agriculture that culd be spread all ver the wrld.译文:他希望他能创造出某种可持续的农业,并将其推广到全世界。分析:that he culd create sme srt f sustainable agriculture为that引导的表语从句,that culd be spread all ver the wrld为that引导的定语从句,修饰先行词agriculture。
    2.The intrductin f these disease-resistant wheat strains led t what is nw knwn as the Green Revlutin,a perid when the prductivity f glbal agriculture increased as a result f new advances.译文:这些抗病小麦品种的引进导致了现在闻名的绿色革命,这一时期由于新的技术进步,全球农业生产力提高。分析:what is nw knwn as the Green Revlutin为what引导的宾语从句,a perid when the prductivity f glbal agriculture increased as a result f new advances为同位语从句,其中,when the prductivity f glbal agriculture increased as a result f new advances为定语从句修饰先行词a perid。
